Telescope Test Fixture 7573980 The telescope test fixture (fig. 2) c o n sists basically of a machined base with provisions for mounting the projector collimator 7573291, and various supports and adapters. The projector collimator is fixed rigidly on one end of the base. At the opposite end is a fixed support capable of mounting the supports and adapters. The movable telescope support, located between the fixed support and the projector collimator, may be moved in either direction on the base to accommodate telescopes of various lengths. The movable support is utilized to secure telescope mount M110 to the base of the fixture. 4 Par. 11,41 a. The projector collimator is an optical device similar to an ordinary straight tube telescope. It does not, however, have an erecting system as do most other telescopes. The collimator serves as a convenient indoor testing target during test and adjustments and final inspection. The target provided by the collimator is always uniform as far as intensity of illumination and clarity of image are concerned. b. The eyepiece end of the projector collimator is machined to accommodate a lamp housing, which is provided with a clamping screw so that it may be secured to the collimator. The lamp housing is equipped with a 7-1/2-watt lamp assembly, an extension cord with a plug, and a switch for connecting to a 110-volt outlet. The collimator contains a reticle pattern which is graduated in mils. The l-mil square at the center is positioned so that any test, adjustment, or inspection necessitating 1/2mil tolerance maybe accurately made. The positioning of the objective lens of the collimator is controlled by the adjustable objective scale. This scale is graduated so the objective can be accurately positioned, setting the collimator to the required distance at which parallax is removed. The scale is graduated with an infinity mark and four other marks representing 500, 200, 100, and 75 yards in range. operation of the telescope mount, are revealed. 12. Fabricated Tools Specially designed tools for inspection of telescope mount M110 during repair and overhaul are listed in table II. These tools may be fabricated for use in depot mainte nance of the telescope mount, but will not be available through supply channels. Dimensional detail drawings (figs. 4 and 5) are furnished herein to enable depot shops to fabricate these tools locally. Table II. Fabricated Tools 11.

Scope This chapter provides specific instructions for the technical inspections by Ordnance maintenance personnel of telescope mount M110 either in the hands of troops or when received for repair in Ordnance shops. It also defines the in-process inspection of materiel during repair or overhaul and the final inspection after repair or overhaul has been completed. 14. Purpose of Inspection Inspection is primarily for the purpose of determining the condition of an item, i.e., serviceable or unserviceable; recognizing conditions which would cause failure; assuring proper allocation of maintenance policies at prescribed levels; and determining the ability of a unit to accomplish its maintenance and supply missions. 15. Categories of Technical Inspections In general, there are five categories of inspection performed by Ordnance maintenance personnel. a. Overall Inspection. This is an o v e r all inspection performed periodically on all materiel in the hands of troops. It Is also performed on materiel received for repair in field or depot maintenance shops. Upon completion of an inspection for serviceability, materiel will be declared either serviceable or unserviceable. This inspection may be limited in scope, such as in inspection of materiel in the hands of troops, or detailed in scope, such as an Ordnance shop inspection. Detailed procedures are presented in section II. b. Preembarkation Inspection. This inspection is performed on materiel in the hands of troops alerted for overseas duty to insure that such materiel will not become unserviceable or worn out in a re- latively short time. It prescribes a higher percentage of remaining usable life in serviceable materiel to meet a specific need beyond minimum serviceability. c. I n - P r o c e s s I n s p e c t i o n . T h i s i n s p e c tion is performed by the repair technician and/or floor inspector in the process of repairing or overhauling the materiel and its components. It insures that all parts conform to prescribed standards, that the workmanship is in accordance with approved methods and procedures, and that deficiencies disclosed by the technical inspection are found and corrected. d. F i n a l I n s p e c t i o n . This is an acceptance inspection performed by a final inspector after repair and overhaul has been completed, to insure that the materiel is acceptable according to established standards. Detailed instructions are contained in chapter 6. e. Spot-Check I n s p e c t i o n . T h i s i s a periodic overall inspection performed on only a percentage of the materiel in each unit to determine the adequacy and effectiveness of organizational and field maintenance. 16. Classification of Materiel All Ordnance materiel is classified as described in a and b below. a. Serviceable. S e r v i c e a b l e p r o p e r t y consists of all new or used supplies which are in condition for issue for the purpose intended and all supplies which can be placed in such condition through preissue tests or inspections, in-storage deprocessing, installation of accessories, correction of minor deficiencies which have developed since the item was last classified as serviceable, application of modification work orders for which parts are available, or assembly of available components. 9 b. U n s e r v i c e a b l e . U n s e r v i c e a b l e p r o perty consists of all supplies which are not serviceable. The definition of unserviceable property is further broken down into property which is unserviceable and economically repairable and property which is unserviceable and not economically repairable. Section Il. INSPECTION OF TELESCOPE MOUNT M110 IN THE HANDS OF TROOPS 17. General This section provides specific instructions for the technical inspection by Ordnance maintenance personnel of telescope mount M110 in the hands of troops. Also, this section amplifies the general instructions contained in TM 9-1100 insofar as the instructions pertain to inspection of this equipment. The inspection procedures and standards listed below apply to all telescope mounts. In general, if the telescope mount M110 is complete and performs its intended function properly, if all modification work orders classified as urgent have been completed, and if all defects as discolsed by the inspection have been corrected, the item may be considered serviceable. 18. Forms and Reports Authorized forms and reports for technical inspections are prescribed in TM 91100. For additional authorized forms and reports for field and depot maintenance, refer to paragraph 3. 19. General Inspection a. Completeness. Examine the instru- ment carefully to be sure that all component parts are present. Particularly check for the presence of ring assembly, nylon pins, setscrews, and boresight screws. b. Appearance. The appearance of telescope mount M110 is an indication of its general condition and will show the treatment it has received. Examine for dented surfaces, bent or broken parts, and other evidence of damage or misuse which might indicate need for repair. c. Engraved Lettering and Indexes. Inspect indexes and lettering to insure that they are clearly defined and easily read. d. Paint and Finish. Inspect for bare spots or damaged finish which expose bare metal surfaces and lead to corrosion. If finish is too badly damaged, a complete refinishing will be necessary. e. Modification Work Orders. All modification work orders must be applied. Refer to DA Pam 310-A and the current modification work order files for modification work orders issued subsequent to this printing. Section Ill. ORDNANCE SHOP INSPECTION 20. General Technical inspection performed by the Ordnance repair shop upon receipt of materiel turned-in for repair, determines the extent of the repairs required and provides the basis for requisitioning the parts, assemblies, or supplies necessary to accomplish the repairs. Often the inspection in the shop maybe the same as that performed by inspectors in the field. It may disclose additional necessary repairs not 10 indicated by the using organization during the field inspection. See FM 9-3 and FM 9-4 for additional information on inspections. See also final inspection portion of this manual. 21. Inspection The inspections given for telescope mount M110 in the hands of troops in paragraphs 17 through 19 are pertinent also to the Ordnance shop. Section IV. PREEMBARKATION INSPECTION 22. General Inspection for outward appearance of telescope mount M110 is of importance as well as inspection of mechanical condition. Where any doubt exists as to the utility of an assembly or of the complete telescope mount, that assembly of the complete telescope mount must be replaced by a truly serviceable item. Equipment, when inspected, must approach new equipment standards of operation and appearance and the workmanship and quality of the end product must reflect the highest standards obtainable. To assure that all items, insofar as practicable, possess original ap- pearance, it is desired that items normally painted be repainted if the surfaces show signs or damage. 23. Inspection a. General. Use pertinent specifications and standards as guides to insure satisfactory performance and acceptability to the telescope. b. Modification Work Orders. Any m o d ification listed in current DA Pam 310-3 or modification work order list, other than those designated as optional will be applied during repair or overhaul. 11 CHAPTER 4 TROUBLESHOOTING 24. Purpose Troubleshooting is a systematic isolation and remedy of malfunction and defective components by means of symptoms and tests. Close adherence to the procedures covered herein will materially reduce the time required to locate trouble and restore the equipment to normal operation. The scope and level of Ordnance maintenance will govern the test and remedies which may be applied. 25.

Was brought to you by me: Liberated Manuals -- free army and government manuals Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it. Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it... They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends? I am setting this document FREE.
